Answer:
The reaction is endothermic
Part A: Yes because there is an immediate reaction of bubbling vigorously.
Part B: It releases energy because when the compounds are added together they are immediately releasing it by bubbling and turning cold.
Part C: Yes because the liquids inside when combined give off coldness that makes the liquid temperature decrease to use this chemical reaction could definitely be used to keep something cold
Explanation:
I know that sulfur/sulphur does. It is commonly known as the sulfur s8 structure.
Answer:
Option A.
Lower air pressure results in a lower boiling point
Explanation:
This is because in an open system, the lower the pressure the lesser the energy that will be required for boiling point. The is little or no collision of air molecules with the surface of the liquid
But if there is increase in pressure, more energy will be required to get to boiling point because there will be strong collision between air molecules and surface of the liquid.
